WARNING!!When tightening the CO2 cap please make sure the threads are properly aligned before tightening. Warranty will not cover replacement of the magazine if you cross thread the cap and ruin the magazines threads.

Not sure what the beef is with this magazine. Mine functions flawlessly.

In the summer months, I'm getting more than 4 full magazines on a single CO2 cartridge; quite a bit less in cooler temperatures. I have experienced no leakage or poor performance with this magazine as others have reported here.

I like to rotate my CO2 and green gas magazines. If you use the gas exclusively you'll wind up cleaning all kinds of excess oil out of your pistol. The CO2 has no oil, so rotating it with the gas mag every other full charge utilizes (and clears out) some of the excess left from using the gas mag. This system works fine for general shooting or airsoft wars, however, if you're target shooting, it's best to stick with one mag or the other as they produce different velocities and groupings for a given distance.

Yeah, the CO2 mag hangs out of the gun a little bit, but if you're not too fussy about the looks, it doesn't hurt anything else.

Using CO2 in the KJW really generates some additional snap to the slide and sometimes with a brand new cartridge the accuracy will be erratic due to the additional initial CO2 charge and I experience some flyers.

Overall though, this magazine is great.

well, I got one of these for my WE tech hi-capa 5.1. I am not very impressed. The co2 produces a lot of kick...for 2 shots. Then the pressure drops so far in the magazine that the slide barely recoils enough to pick up the next BB from the magazine. That was tested on a day that was 95 degrees in the shade. I barely got one magazine of BBs off before the co2 was gone. However, this magazine worked great in my friend's 4.3. Just not good for the massively heavy slide of the full-size 5.1. Just not worth the money you spend on co2. Better off buying propane.

I got this mag yesterday and after about 11 co2 cartridges, the mag started to leak. You have to screw the cap on very fast and tighten it a lot or else it leaks. Good metal construction and feeds great, sticks out of the bottom of the gun which sucks. Buy the green gas mags. also there is no lube in co2 so it is bad for your gun, mine barely functions. Piece of crap

use this if you want a real pistol... CO2 is cheap and easy to get. Oh, by the way, does anyone want 50 more fps... going once... going twice... I DO!!!!! These are awesome and the capacity is great, a great buy.
